is there some way of sighting in so that your rifle can be used for close range or long range without re-sighting.
 
Rapid Z reticle from Zeiss if you know your ballistics, if that is what I think you are after.No touching the adjustments this way.Not sure if it is the best though for precision shooting.
 
You can also go out and test it at long and close ranges, and record the settings on the scope. For example, you could "zero" your elevation turret at 100m, then turn it a few clicks (that you write down or memorize) and you would now be ready to shoot at your new distance. As an example, when I shoot with my elevation turret set to "0" at 100m, to adjust to 300m I set my elevation turret to "15".
 
A Mil-dot or similar scope will work. Cross-hair out to 100. Then hash marks (Mil-dots) as you get farther away. You have to shoot at the different ranges or be able to do the calculations to figure out which to use at which distance, but once you know that the 2nd down is 200 yards and 6 down is 400 yards you never really have to adjust your scope.
 
Part of working up a load can be documenting its performance at various ranges/conditions. Many shooting logbooks have this sort of information for various pet loads, and allow for quick calculation of hold-offs from a specified zero.

Also, if you do some reading on the concept of "point blank" (which doesn't mean what most non-shooters think it to mean), you can see that a properly zeroed rifle will have a large range interval at which the point of impact will be close enough to the point-of-aim for the desired effect. For example, if hunting a large mammal, your round might be reliably lethal as long as it hits within 4 inches of a specified aim point. The rifle might then be useful for the interval of ranges where the POI is plus or minus four inches from the POA -- which could be quite a large range.

A good varmint rifle zeroed to around 200 yards might be reliably lethal to a standing ground squirrel, aimed center-of-mass, at ranges from 50 to 300 yards without adjusting the point of aim.

Precision target shooting is usually known-distance shooting, so you ordinarily sight your rifle to the specified distance.

Mil-Dot. IMO the best reticle. Here's my attempt to photograph through my HiLux.

You get the idea.

What I did was to place my rifle in a cradle, put a ruler out to 100 ft, and at each zoom I recorded the inches each dot was on. I then extrapolated those numbers out to the respective distances I would set for each zoom. For example, I always use 10x for 300yrd, 12x for 400, 14x for 500 and so on. I then know how many inches each dot is for each distance as such in this.

This is all just mathematical, what may happen. I have yet to fully test this. But I do know it is close. Reality is always correct.

i meant like using a .308 or .223 for 100-400m (not the best for a .223 i know, but i'd still like to know)

lol, 2nd down at 200y would be a 14.4" bullet drop. If your gun does this.... throw it away !

Just a little technical fun there. :p

Mil dots are pretty simple but still more for the advanced shooter.



There are simple solutions for what your looking for however.

- lots of scopes out there have BC reticules that are set up for a rifle cal and give you cross hairs were the bullet should impact at varying distance. Thease work pretty dam good some times. You get best results with a first focal plane ( $$$ ) or a fixed zoom scope.

- Custom turrets like on the G7 from nightforce are your other option. Your ranges are marked right on the turret. you just spin and fire. what level of zoom your on has no effect. VERY good feature.



They both work fine for hunting but will never always be bang on at all distances marked.

advanced shooters will record data of the weather and altitude at least, every time they shoot. They make there own dope charts ( drop on previous engagement ) so to know how much real life drop is expected in the closest conditions.
 
ashmaiz, bottom line is nothing beats getting to the range and watching what happens, both with your own rifle, but what others are doing and why. Expect to take time to get yourself comfortable, and a lot of ammo.
 
i know thiss hould prob. be a second topic, but are there any longer range shooting ranges near toronto, or should i be going to crown land
